Our institute was originally founded at Osaka University as the Welding Research Center in 1969 on the advice of the Science Council of Japan, to meet academic and industrial requirements. Subsequently, the institute was formally established in 1972 as the Welding Research Institute. The purpose of the institute was to perform research in all aspects of welding engineering. The institute was reorganized into the Joining and Welding Research Institute (JWRI) in 1996 to meet the increased demand for “joining” in industry, and because of the diversification required by the trend towards globalization in manufacturing and in response to scientific and technological progress. Furthermore, JWRI was recognized as a Joint Usage/Research Center by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) in 2009. JWRI has energetically promoted both fundamental and applied research from 1972, and has since become the only institute in Japan, and also the world’s leading institute, in the field of welding and joining.

Universities now operate in a global and highly-diverse environment, and are required to create technological innovation through research activities that ascertain scientific truths and further the sustainable growth of society, and to develop personnel who can contribute to these goals. If, on the other hand, we change our viewpoint to our daily life, we can note that there is a large variety of items such as smartphones, tablets, domestic electrical appliances, automobiles, airplanes, ships, skyscrapers, electric power plants, and rockets, artificial satellites and other spacecraft. These items are produced and/or constructed by manufacturing industries, which are a proud specialty of Japan. And further, these items are produced and/or constructed using welding and joining technologies.

The purpose of JWRI is to contribute to the sustainable growth of human society through technological innovation in welding and joining in the three research areas of “Process”, “Metallurgy” and “Design & Evaluation” and also in a research center that explores the future of joining science. Accordingly, in JWRI, three research divisions for fundamental and applied research, namely “Materials Joining Process”, “Materials Joining Mechanism” and “Materials Joining Assessment”, and also a research center, the “Smart Processing Research Center” for advanced research with a focus on the nanoscale, work closely together and perform world-leading research in the field of welding and joining. Furthermore, JWRI as the Joint Usage/Research Center on Joining & Welding annually accepts “Joint Research Collaborators” amounting to more than 200 professors and researchers, who belong to about 70 other universities and public research institutes in Japan, and has established the “JWRI International Joint Research Collaborator (JIJReC)” program. JWRI is also promoting an inter-university cooperative research project that involves 6 institutes from different universities, supported by MEXT. JWRI therefore plays an important role as a world center of excellence in the field of welding and joining.

One of JWRI’s important features is to conduct very active collaborations with industry, under the “tradition of practical science” in the Osaka University Charter. JWRI promotes collaborations with private companies and accepts provision of “Research Alliance Laboratories” and “Joint Research Chairs” funded by private companies. On the other hand, from the viewpoint of education and development of personnel in JWRI, generally 100 graduate students and undergraduates who belong to Faculty of Engineering, Osaka University study at JWRI every year. JWRI established the “International Welding Engineer (IWE) Course” in 2008 to develop highly-professional practitioners in the field of welding and joining. Furthermore, JWRI is promoting the Project “Research and Educational Hubs for Innovative Manufacturing in Asia”, supported by MEXT from 2013. This project arranges internships that bring together students from the sciences and the humanities, known as “Coupling Internships” (CIS), at private Japanese companies located in Asia, which cultivate global leaders with a practical mindset.

Our JWRI will pass its 50th anniversary at 2022. JWRI will perform the research relevant to the demands of society in the 21st century and also to the vision of a successful global society in the 22nd century. Our staff will make continuous efforts to achieve the present and future targets. Our JWRI will play an important role in contributing to the sustainable growth of society through technological innovation in welding and joining.
